推荐答案

您无需执行任何特殊操作.只需为您的发行版获取Tesseract OCR设置，然后在系统上安装 .确保您的PATH变量具有Tesseract主目录的条目，并且已设置TESSDATA_PREFIX变量并指向Tesseract主目录.重新启动Solr，您一切顺利.通过/update/extract处理程序将文档推入索引时，您应该能够看到OCR组件.

You don't need to do anything special. Simply get the Tesseract OCR setup for your distro and install it on the system. Make sure your PATH variable has an entry for the Tesseract home directory, and the TESSDATA_PREFIX variable is set and also points to the Tesseract home directory. Restart Solr and you're good to go. You should be able to see the OCR component when you push documents to the index through the /update/extract handler.

默认情况下，Tesseract仅随附英语模型.从此处获取其他语言的模型.

By default, Tesseract only ships with the English model. Get models for other languages from here.
